This invention relates to a refrigerator case adapted to be placed in a show WlIlClOW,

p the formation of frost on the show window in front of the display chamber.

The. specific construction will be more particularly described in connection with the accompanying drawings, which illustrate the inventionin its preferred form.

In the drawings:

Figure 1 is an elevation of the invention as viewed from the interior of the store.

Figure 2 is a horizontal section through the refrigerator case and the window adjacent to which it is located, the section being taken on the line 2-2 of Figure 5.

Figure 3 is "an enlarged 'de'tail'view showing the connection between the refrigerator .case and the window.

Figure '4 is a section "taken on the line 4-4 of Figure 5.

Figure 5, is a section taken on the line 5-5 of Figure 4.

The refrigerator case, which forms the subject matter of my invention, is adapted to rest upon a latform 10 in front of a show window 11. The case is preferably rectangular in shape with heat insulating walls, and its lower part, which is used for display purposes, is provided on its inner side with doors 12, and on its outer side, adjacent to the window 11, with a double transparent wall 13. The doors 12 extend substantially the entire length of the case, so that an adjust-ably supported wire shelf may be inserted in the case to receivethe articles to be displayed. The ends of the dis lay chamber are lined by mirrors 14, and t e inner faces of the doors 12 are also lined by mirrors, as indicated at 15.

The upper part of the case is for contain ing ice, which is inserted through a door- 16, and rests on plates 17, which are composed of metal, porcelain or the like. These plates slope downwardly toward the middle of the ice chamber, and are supported by bars 18, which rest on cleats 19 secured to the end walls of the refrigerator case. The ice is prevented from coming in contact with the front andrearwalls'bf the-refrigerator cu'se by vertical partitions 20 and 21, which are spaced sufficiently from the wallsof the case to form passageways 22 and 23 for the circu lation of air. I I

The plates 17, on which the ice rest-s, are formed attheir inner edges withdownturned ;lips 24, which overhang a'drip pan- 25, having a'draln pipe 26 leading from one end thereof. An electric lamp 27 is located in the upper part of'the display chamber be tween the windows 13, so that it will not be readily visible to passers-by. The lamp 27 is also located immediately beneath the space 22, so that whatever airis heated by radiation from the lamp rises through the space 22, and does not come in contact with the goods displayed. As the air thus rises, its place is taken by air which has'been chilled by the ice, and which circulates downwardly between the plates 17, underneath the lips 24, and over the edges of the pan 25.

The refrigerator case is also arranged so "that'theformation of hasten the window 11 .in front of the display chamber will be prevented during cold weather, and a clear view oft'he goods displayed inside the window may always be obtained by passers-by. It is well known that frost is commonly formed on windows during cold weather and that it makes the windows opaque, so that the goods displayed cannot be seen. In order to prevent this, the wall of the refrigerator case has a rubber strip 28 secured to its edges, which strip may be pressed against the window so as to form a substantially airtight connection therewith. On the upper edge of the wall, the rubber strip is formed trough shaped, as indicated at 29, so that when frost is formed upon the upper part of the window above the refrigerator case and subsequently melts, the water thus formed will be conducted to one side of the refrigerator case, and will not trickle down the windowin front of the display chamber, and subsequently freeze and obscure the view. The warm humid air is thus prevented from coming in contact with the portion of the window which is in front of the refrigerator case. When placing the refrigerator case in os ition, a moderate compression of the ruber stri s 28 and 29 will cause them to grip the win ow, so that they will not readily 'th'elspecific 'copstr uc'ti on fangl Tifel'a t' idi; the Various elements without "any ma fgatial depix-flute from the s a'lielii t feat fires f {tli i'nventio'n asexpressed in the claims.
